What counts as a private island in Thailand?
You want a beach where the only footprints are yours, and staff who appear only when you need them. A private island stay in Thailand comes in three kinds. The first is a resort that takes up a whole small island. The second is a resort on a quiet island that it shares with a fishing village. The third is an exclusive-use buyout, where your group books every room for a few nights.
Many of Thailand's most beautiful islands sit inside national parks and cannot be built on, so true whole-island resorts are few. That is why the second kind, a calm island with one excellent resort, is our call for most groups. Our experiences hub shows other ways to spend time on the water.
The best private island resorts in Thailand
The best private island resorts in Thailand sit off Phuket, Koh Samui, Rayong and Koh Kood. Each entry below gives the island, the sea it sits in and how you get there. We include only resorts we could confirm as operating in November 2026.
The Naka Island, a Luxury Collection Resort & Spa (Phuket). It stands on Naka Yai Island, in the bay off Pakhlok on Phuket's east coast, and is listed as operating. The island sits in calm water close to the main island, so the boat ride is short. We arrange the transfer from the pier when you book.
Cape Fahn Hotel (Koh Samui). The hotel has its own islet off Choeng Mon Beach in the north-east of Samui. From Samui Airport, a short drive takes you to its lounge, then a 3-minute crossing by boat or by truck, depending on the tide. The hotel runs this transfer daily from 07:00 to 23:00.
The Racha (Koh Racha Yai). A boat from Chalong Pier on Phuket takes about 30 to 40 minutes, depending on the sea, the resort says. Koh Racha Yai is a small island south of Phuket with clear water for swimming and diving.
Koh Munnork Private Island (Rayong). A small island resort in the Gulf off Rayong, listed as operating. Rayong is on Thailand's east coast, much closer to Bangkok than the southern islands, which makes it useful for a short break.
Soneva Kiri (Koh Kood). A villa resort on Koh Kood, one of Thailand's largest islands, near the Cambodian border. It is not a private island, but its beach and its forest feel far from everything. See our Soneva Kiri review.
Six Senses Yao Noi (Koh Yao Noi). Listed as operating, it holds Two MICHELIN Keys (2026 guide). Its pool villas look out over the limestone islands of Phang Nga Bay.
How much is it to stay on a private island?
The cost of a private island stay depends on the season, the size of the villa and whether you book rooms or the whole island. Each resort publishes its own room rates on its website, and those rates change with the season. A whole-island buyout is quoted to your plan.
For a buyout, the price also depends on how many nights you stay and how many staff the resort brings in. A chef, a boat or a wedding set-up adds to it. We ask each resort for a written quote for your dates and lay the options side by side. Then we give you our view on which one is worth the money.
Can I buy a private island in Thailand?
In practice, no. The Department of Lands states that foreigners generally cannot own land in Thailand in their own name, except where the law expressly allows it. A foreigner can own a building on leased land, and a registered land lease runs for up to 30 years per term.
Renewal options in a lease are contract terms; the law does not guarantee them. The freehold route for foreigners is a condominium unit, where foreign ownership in one building may not exceed 49% of the floor area. If you want to look at property, we introduce you to a trusted property agent and an independent lawyer, on request. Read our guide to buying property first.
An island to yourself for a day
The lighter version of a private island is a day on a quiet beach by private boat. You leave in the morning, swim off an empty beach, eat lunch on board and come back before sunset. It needs no buyout, and it works for a couple, a family or a small group.
Example plan. Land on Samui and drive to the Cape Fahn lounge. Cross to the islet in three minutes. Next morning, a private boat takes you to a quiet beach for a swim and lunch on board. You are back by evening for dinner from a private chef.
Most of the best beaches are in national parks, so park rules apply. Boats moor only at buoys or piers. The Department of National Parks charges foreign visitors ฿100 to ฿500 per adult, depending on the park. Sunscreen with oxybenzone and similar chemicals is banned in all parks, with fines up to ฿100,000. Maya Bay closes every year from 1 August to 30 September, and swimming there is never allowed.
See our private island day charter. For a longer day at sea with several stops, we plan a route around the islands near your hotel.
When to go
The best months depend on the coast.
Our guide to the best islands in Thailand compares the seas month by month.
Getting there: speedboat or helicopter
Most private-island transfers are by the resort's own speedboat. Helicopters can land at the main airports, where they use the runway, but only a few resorts have their own helipad. We name a helipad only when the resort's own site shows it; Anantara Layan on Phuket is one.
Cape Kudu on Koh Yao Noi is a good example of a typical island transfer. It is a 20-minute drive to Ao Por Grand Marina and a 30-minute speedboat to Manoh Pier. Then comes a 10-minute car ride, the hotel says. Read more in our Koh Yao Noi guide.
Plan it with Tanner
Tell Tanner who is coming, your dates and how private you want it to feel. One planner picks the island, books the villas or the whole resort, and arranges the boat, the transfer and a chef. That works for two guests or a full wedding party. We also tell you when a private island is only a resort with a long jetty.
